Step-by-step explanation:

Answer 2

Answer:

In the figure, AC is the chord and OB is a perpendicular drawn from the center O on the chord.

Radius of the circle, r=OC=17 cm

Perpendicular length, OB=8 cm

Now triangle OBC is a right-angled triangle.

From Pythagoras theorem,

=15 cm

Theorem: Perpendicular drawn from the center of a circle to the chord, bisects the chord.

So, length of the chord AC=2BC=30 cm
